Kinetic analysis and chemical bond breakage of bagasse pyrolysis process

In the present study, thermogravimetric analysis was used for investigation a bagasse pyrolysis. Multi-period models were applied for evaluation of kinetics parameter based on the TG curve. The decomposition bagasse process was undergone four periods via the breakdown of each different chemical component in a sample. The dehydration occurred below 170 degrees C; hemicellulose primarily and cellulose partially decomposed in a range of 170 to 318 degrees C and cellulose continuously decomposed from 318 to 400 degrees C. The temperature range of 400-700 degrees C for the last period showed the evidence of lignin decomposition. The study also identified activation energy constant (E-a), the pre-exponential factor (A) and reaction order (n) for each period of pyrolysis process. The dependence of the breakdown of the specific chemical bond on the pyrolysis temperature was also proven by FTIR spectrum analysis.
